The novel efficient procedure has been developed for the conjugate addition of amines to electron deficient alkenes. The results showed that the catalyst was very efficient for the reactions with the excellent yields in several minutes. Operational simplicity, without need of any solvent, low cost of the catalyst used, high yields, reusability, excellent chemoselectivity, applicability to large-scale reactions are the key features of this methodology. The article is published in the original.
Functionalized cyclobutenes via multicomponent thermal [2 + 2] cycloaddition reactions

(Chemical Equation Presented) Enamine [2 + 2] cycloadditions can be achieved in useful yields simply by stirring a mixture of an aldehyde, diethylamine, a dialkyl fumarate, and potassium carbonate in acetonitrile at 25°C, conditions that are compatible with the presence of a potential leaving group on the β-position of the intermediate enamine. Methylation and elimination of the product cyclobutanes completes a mild nonphotochemical route to functionalized cyclobutenes.
ADDITIONS DES FONCTIONS >NH ET >P(O)H SUR LA DOUBLE LIAISON DES VINYL SPIROPHOSPHORANES SYNTHESE DES α ET β AMINO SPIROPHOSPHORANES ALCOOLYSE DE LA LIAISON P-C DANS LES COMPOSES D'ADDITION OBTENUS

Addition of amines and of hydrogenphosphonates on the carbon-carbon double bond belonging to vinylphosphoranes is examined.The stereochemistry and reactivity of the saturated adducts obtained is rationalized.Alcoholysis of the P-C bond is also studied.
